MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Nov. 12, 1918.

Originalappllcation filed March 27, 1916. Serial No. 86,958. Divided andthis application filed February 18, 1918. Serial No. 217,771.

To all whom it may concern a curved path.

. in the several figures.

This invention relates to mechanical movements and hasfor its generalobject to devise a mechanism that will impart to a driven member abodilv tiransferrmg movement in The invention will be herein disclosedas embodied in a mechanism designed to oscillate a member bodily in asubstantially U-shaped path, but it will be ob.- vious from anunderstanding of the invention that it is also applicable to mechanismsdesigned to move a member in paths other than that specificallydescribed but which involve similar problems of motion.

The nvention will be readily understood fromthe following descriptionreference beinig niade to the accompanying drawings in w ich,

, This application is a division of m pendmg application Serial No.86,958 file March 27, 1916 for improvements in heel lastin'g machines.The machine shown in said application comprises mechanism for wiping themargin of the upper at the heel part of the shoe into lasted position onthe sole receiving face of the insole and a tacking mechanism that ismoved automatically around the marginal portion of the heel and of theinsole and operates durin said movement to drive tacks through the astedupper to secure it in its lasted position. The mechanism shown in thepresent application forms a part of the mechanism that guides the tackeraround the heel and of the shoe.

It obvious that in the machine shown in my parent applicat'on the.tacker must be moved in a subs'ta tially U-shaped or horse-shoe shapedpath. This movement is imparted to the tacker by the driven member 2which consists of a post on which two plates 3 and 4, respectively, areloosely mounted so that they are compelled to partake of the bodilymovement of the post 2 but can swing or pivot on this post. In otherwords, themember 2 forms a pivot pin for the plates 3 and 4. This 0stpasses through a U-shaped slot 5 former in a plate (3 that is rigidlysecured to the. frame 7 of the machine. It is held against verticalmovement reiativel to the plates 3. 4 and 6 by means of a head 8 thatengages the lower face of the plate 6, and a nut 9 that is threaded onto the upper end 01' the. post 2 and brings up against a shoulder whichprevents it from binding the plates 3, 4 and 6 together.

A slide 10 is mounted to reciprocate in a horizontal way formed betweenthe plate 6 and the. frame 7 and has fixed to it a rack 11, as clearlyshown in Figs. 1, 2 and 3. Another slide 12 is similarly mounted in theopposite side of the frame and has a rack 13 fixed thereto. Both racksare reeiprocated bv a pinion 1-1 mounted fast on the upper end of arotatable shaft 15 which is oscillated through considerably more thanhalf a revolution by mechanism that comprises a worm wheel 16, fast onthe lower end of the shaft 15, and a worm 17 that drives the Worm wheel16. This mechanism reciprocates the racks and consequently the slides 10and 12 back and forth in their Ways in opposite directions. The twoslides 10 and 12 run tangent to a disk'lS fast on the upper end of theshaft 15, and this disk is provided with a semi-c lindrical notch orrecess 19 (see Fig. 4) w ichreceives the post 2 when this member is inthe curved part of the slot 5 and which is designed to register withsimilar notches 20 and 21, re

spectively, formed in the slides 10 and 12, re-

s ectively. As clearly shown in Fig. 2 the disk 18 is positioned in arecess formed for it in the lower face of the platetii so that when thepost 2 is positioned in he notch 19 of the disk 18 the face of the postopposite the notch is engaged by the wall of the slot 5. The post thusis compelled to move with the notch.

Referring now to Fig. l, and assuming that the slides 10 and 12 aremoving in the directions indicated by the arrows and also that the postis positioned in the notches 19 and 21, which at this time are inregister, the continued movement of the parts in the directionsindicated enables the slide 12 to carry the post toward the left alongthe leg a of the U-shaped slot 5. The direction of rotation of the worm17, and consequently of the pinion 14 and disk 18, is reversed at orabout the time that the post 2 reaches the end of this leg of the slot,whereupon th slide 12 moves the post back toward the right (Fig. 1)along the straight part n of the slot 5 and toward the curved portion.\Vhen the post arrives at the position in which it is shown in Fig. 1the notch 19 in the disk 18 engages it and carries it around the curvedpart of the slot 5 and delivers it to the notch 20 of the slide 10,which then carries it along the straight part I; (Fig. 1) of theU-shaped slot 5. When the motion of the disk 18 and slides 10 and 12 isagain reversed the motion of the post is reversed and this action iscontinued so long as this mechanism is allowed to run. The post :2.being free to rotate in the parts 3, -l and 13, rolls along the walls ofthe slot 5 with comparatively little friction. It will be noted that theedges of the slides 10 aml 12 which are tangent to the periphery of thedisk 18 lie on the pitch line of the racks 11 and 13.

From the foregoing description it will be understood that the slidescarry the dri"cn member 2 along the straight portions of its path oftravel while the disk lti carries this member around the curvedpol'lloli oi its path of movement aml transl'crs it from .one of thereciprocating devices to the other at the proper times in its movement.This movement of the member 2 moves the plates 3 and 4 in a U-shapedpath. but since these plates can have a 'pivotal movcnu-nt relatively toeach other about the axis of the postu2 certain variations in this pathcan be produced by suitable mechanism as clearly explained in my parentapplication above designated.

The mechanism for driving the worm I7 is not shown herein since anysuitable form of automatic reversing mechanism may be. used. it the uechanisln driving the worm 17 operates at a uniform spccll between itspoints of reversal. the post 2 will be moved along the slot 5 at annil'orm rate ol travel. it is desired to give lhc post .4 a tep by stepmovement alon its path, it is me ely nece sary to drive the worm 1Tintermittently by any one of several well known mechanisms.

'hile I have herein shown and dcscribcd the best clnbodimcnt ot' theinvent ion of which I am at present aware. it is ohvious that thisembodiment may he modilicd in many ways without departing from thespirit or scope of the invention. 'lt is obvious also that theunderlying principles of the invention are applicable to mechanismsdesigned to move a member in a ditl'crcnt path from that in which themechanism dcscribed moves the post 2 but which involve similar problemsof motion.
